Is there any suggestion of this issue? Thanks!

Can you try:

fig, ax = plt.subplots()
cm = plt.cm.get_cmap('Greys')

sc = ax.scatter(df['x'], df['y'], s=500, c=df['score'],
                vmin=df['score'].min(), vmax=df['score'].max(), cmap=cm)
cb = fig.colorbar(sc)
t = cb.set_label('score', rotation=-90)

ax.set_xlim( [-0.5,9.5] )
ax.set_ylim( [-0.5,9.5] )
ax.set_xlabel('x')
ax.set_ylabel('y')

plt.tight_layout()
plt.show()

Output:
